Referring to the'dr'awing in detail, the reference character T indicates tractors, which are coupled in parallel relation with each other by means of the coupling device forming the essence of the present invention.

Each tractor embodies side rails 5, and the usual front wheels 6 for supporting the forward portion thereof. As illustrated by Fig. 1, the side rails 5 of each tractor are arranged in parallel relation with each other and constitute angle bars, the flanges 7 thereof being designed to fit within the grooves formed in the sides of the coupling members 8 so that the coupling members will be securely held in position.

These members 8 have depending end portions 9 that are provided with openings to accommodate the outer ends of the drive shaft- 192e- 'slriarnog 106,245:

Arms 23- are connected to the opposite sidesof the members 8 and extend rearwardly where they are provided with openings to receive the er ends of the shafts 20.

The draftgba'r' fe tion incl-lid sf g a part ofthe inveneise bar 24 formed with heads ds, which heads are positi0ned; V v socket members 26 that are provide'dwith'flanges 2-7 which in turn are forme *vit-h openings to receive the rivets 28 --fq e'curingthe socket members in position or i f -tractor frame.

This bar'Q t has jcenhection with the adjacent rearwardly extended plates 18 of the tractors, and is formed with a central opening to accommodate the rod 29 formed with an eye 30 at its read'end, the forward end thereof being supplied with a nut 31 acting pendently of each'other throu as a seat for one end of the coiled spring 32 The opposite endof the spring 32 contacts with the bar 24 as-shown by Figureso that the agricultural machine which may be connected to the draw bar through the medium of a suitable chain, cable or the like, which may be passed through the eye 30will direct the initial strain to the spring 32 relieving the rigid eiements' of the draftbar of unduestrain.

Power is transmitted from the sprockets" ll to the substantially large sprockets 35 through the medium of the chains 36; and it-will be obvious that the wheels 19 will operate indeh the engine 37 and drive shaft 38 associated therewith,

with the result that should it be desired to turn the coupled tractors to the right, the wheel 19 at the right of the device will be thrown out of: operation 'by means of the usual clutch mechanism not shown, whereupon the opposite wheel 19 which continues to operate will push the machine to the right, to the end that the steerin -may be accomplished by the application 0 power to certain drive wheels 19. 1

From the foregoing it will beseen that two substantially small tractors niaybe connected to increase the power of the tractor two tractors for heavy duty work. I

It will of course be understood-that the usual front wheels and connecting elements of a tractor must be replaced by freely castering wheels which require no direct control, the steering being accomplished by the manipulation of the clutches to change the speeds of the tri ctor drive wheels.
